The Nature Conservancy and the Block Island Conservancy co-sponsor free, guided nature programs on Block Island throughout the year. Together, we offer many different ways to connect to the fields, marshes, and beaches that make the island so exceptional.

In addition, The Nature Conservancy offer a series of special events in honor of James Stover, a boy who loved exploring Block Island.

A Last Great Place

In 1991, The Nature Conservancy named Block Island one of 12 “Last Great Places” in the western hemisphere. This special designation highlights the island’s abundance of rare plants and animals and the community’s unique support for conservation. The Conservancy set up a permanent field office on the island soon after, affirming our long-term commitment to protecting the nature of Block Island.

Today, nearly half the island is permanently protected for people and nature. It remains a wildlife hotspot, providing habitat for many plants and animals that disappeared from the rest of southern
New England decades ago. The Conservancy’s Block Island Program maintains over 2,000 acres of habitat, offers hands-on discovery programs, and supports groundbreaking scientific research in the Great Salt Pond.

For all of this, we thank our supporters and partners -- many of whom have been with us since the very beginning -- for their generosity, trust, and vision for Block Island.

Places to Visit


From the open grasslands at Lewis-Dickens Farm Preserve, to the narrow paths atop the Clay Head bluffs, the Greenway Trails of Block Island will show you something new every time. 
To be a good visitor and to help us protect this special place, we ask that you observe the following guidelines:
• The best way to explore the Greenway Trails is on foot. 
• Please do not bike on the trails. The island’s many dirt roads offer excellent off-road biking opportunities.
• Please respect all signs marked “private.”
• Lyme disease is common on Block Island, unfortunately. Take precautions to avoid deer ticks.
• Staying on marked trails will help you avoid ticks and poison ivy.
• Dogs are permitted, but please keep them leashed.  They can disturb wildlife and other hikers.
• Take only photographs, leave only footprints.
Please remember that the dunes and bluffs are very fragile. Please stay clear of them for your safety.
